The keto diet (also known as ketogenic diet, low carb diet and LCHF diet) is a low carbohydrate, high fat diet. Maintaining this diet is a great tool for weight loss. More importantly though, according to an increasing number of studies, it helps reduce risk factors for diabetes, heart diseases, stroke, Alzheimer’s, epilepsy, and more1-6.On the keto diet, your body enters a metabolic state called ketosis. While in ketosis your body is using ketone bodies for energy instead of glucose. Ketone bodies are derived from fat and are a much more stable, steady source of energy than glucose, which is derived from carbohydrates.

The best place to get started if you’re interested in the ketogenic diet is to first take a look at the fats you can incorporate, such as avocado, olive oil, or cacao butter. You could also take a look at more of an animal-based fat like grass-fed tallow or pasteurized lard or, if you are not too sensitive to butter, grass-fed butter is a really good option.

The second tip is to “carb-up”, meaning to eat high fat, low carb all day, and at night basically eat all carbs, no fat. Carbs like sweet potatoes, plantains, and grains, are some of the prefered foods when practicing “carb-up”. The reason why the “carb-up” practice can be helpful is because, once you are fat-adapted, your body burns carbohydrates first, and then goes into the fat-burning mode but, once you increase the amount of carbs eaten, your body’s ability to better burn fat is increased. To sum up “carb-up”: helps you go from fat-adapted back to the fat-burning mode.

For athletes, research on the keto diet highlights potential improvements in athletic performance, especially when it comes to endurance activities. An article suggests ketogenic-type diets may allow endurance athletes to rely mostly on stored fat for energy during exercise rather than having to refuel with simple carbohydrates during endurance training and competition while additionally improving recovery times.

Basically, fat within your blood travels as lipoproteins, along with cholesterol, proteins, and phospholipids. In order for an artery to be “clogged”, there needs to be a small tear in its inner wall first. These tears can be due to stress, smoking, a highly-processed diet, etc. In order for the walls to be repaired and thus prevent “clogging”, Vitamin E must be used. Vitamin E, being a fat-soluble vitamin, requires fat in order to be available for your body to use. Therefore, the consumption of fat can help your arteries self-heal and thus prevent “clogging”.
The biggest shifts in your daily habits will be how you food shop and how you cook, and recipes that are ketogenic need to be followed rather than just low-carb. You will require the healthy fats in order to get into ketosis and have enough energy without the carbs. And you will be considerably more energetic and healthier when cooking your own keto-friendly food rather than buying supposedly keto foods off the shelf. So visit my page on keto recipes as well as keto snacks (including fat bombs!), and get started on a ketogenic meal plan!
Although the exact role of the ketogenic diet in mental and brain disorders is unclear, there has been proof of its efficacy in patients with schizophrenia. And, to boot, the ketogenic diet works to reverse many conditions that develop as a side effect of conventional medications for brain disorders, like weight gain, type 2 diabetes and cardiovascular risks. More research is needed to understand the role of the ketogenic diet in treating or improving schizophrenia, as the current available studies are either animal studies or case studies, but the benefits of a high fat, low carbohydrate diet in neurology is promising.
If you do try the diet outside of medical supervision, Kizer says it’s important to test your urine with urinalysis ketone test strips to ensure your ketone levels don’t become dangerously high. Ketone urine test strips are also used by people with diabetes to determine if they’re at risk for ketoacidosis (DKA), a life-threatening complication that occurs when an individual doesn’t have enough insulin in their body. (Healthy ketosis is considered 0.5 to 3.0 mM blood ketones.)Aside from carb flu, be warned that staying in long-term, continuous ketosis may have drawbacks that may actually undermine your health and longevity. To stay on the safe side, I recommend undergoing a cyclic ketogenic diet. The "metabolic magic" that ketosis brings to the mitochondria actually occurs during the refeeding phase, not during the starvation phase.

In the first week, many people report headaches, mental fogginess, dizziness, and aggravation. Most of the time, this is the result of your electrolytes being flushed out, as ketosis has a diuretic effect. Make sure you drink plenty of water and keep your sodium intake up.6One of the fathers of keto, Dr. Phinney, shows that electrolyte levels (especially sodium) can become unbalanced with low carb intake.

To see whether I was a good fit for the keto diet, Wali requested I have some lab work done, including a cholesterol panel and a fasting-insulin-level test. My results came back normal, meaning there was no medical necessity for me to go on the diet. If I were pre-diabetic or insulin-resistant, Wali would likely have made the keto diet part of my treatment.
Increasing numbers of people around the world are suffering from chronic diseases such as diabetes and obesity, and the main culprit is usually the food they eat. The standard American diet, for example, consists of excessive amounts of protein, processed grains and carbohydrates — particularly in the form of refined, added sugars — none of which is good for your health.

There are variations of the ketogenic diet that are implemented for a variety of reasons. One of the top reasons these variations are used are for athletes who are not getting the necessary energy required for their intense workouts. There are also those who enjoy the benefits of ketosis, but they just do not feel the same without a carb refeed day every now and then.
Hi Sia, welcome to the wonderful world of keto! I would start simple – eat whole foods like avocado, protein, and dark veggies. Download MyFitnessPal or CarbCounter apps to track your macros for you. What works best for me is planning out my meals ahead of time. Ill meal prep my food then log it into MyFitnessPal app so I know I am on target then the next day, eat only what I’ve logged. Its the perfect way to make sure you have enough food that already prepared and the best way to stick to macros. Hope that helps!
On the other hand, the types of foods you’ll avoid eating on the keto, low-carb diet are likely the same ones you are, or previously were, accustomed to getting lots of your daily calories from before starting this way of eating. This includes items like fruit, processed foods or drinks high in sugar, those made with any grains or white/wheat flour, conventional dairy products, desserts, and many other high-carb foods (especially those that are sources of “empty calories”).
It feels like everyone is talking about the keto diet — the high-fat, low-carb eating plan that promises to turn your body into a fat-burning machine. For that reason, keto has surged in popularity over the past year as a lose-weight-fast strategy. Thank Hollywood A-listers and professional athletes like Halle Berry, Adriana Lima, and Tim Tebow who’ve publicly touted the diet’s benefits, from shedding weight to slowing down aging. Here’s everything you need to know about going keto — and how to do it the Bulletproof way.
Following a diet that drastically restricts carbohydrates requires carefully monitoring your food choices to ensure you are meeting your nutritional needs. Working together with a registered dietitian can make sure you follow this diet in a healthy manner without increasing your risk for complications or negative side effects. You can find a registered dietitian at EatRight.org.

Totally agree that it’s not something for everyone, though. Even one of the authors I read said he sometimes sneaks a french fry or a bite of cheesecake/ice cream, though he’s able to stop after just a little bit and it doesn’t throw him off horribly. Of course, that’s not license to eat junk all the time, but it does mean that once you’re well-adapted, you can sometimes indulge.

When it comes to weight loss — a big possible draw of the plan for many individuals — the benefits of the ketogenic diet may not be much different from any other diet plan. “There is no magical weight loss benefit that can be achieved from this diet,” says Spano. “The ketogenic diet may help weight loss in the same way other diets help — by restricting food choices so you eat fewer calories.”

After about two to seven days of following this eating routine, you go into something called ketosis, or the state your body enters when it doesn't have enough carbs for your cells to use for energy. Then it starts making ketones, or organic compounds that your bod then uses in place of those missing carbs—and oh, it also burns fat for more energy, says Beth Warren, R.D., founder of Beth Warren Nutrition and author of Living A Real Life With Real Food.
Because the main tenet of the keto diet is counting and cutting carbs — a commonly used way to control blood sugar — this eating approach has become increasingly popular among people with type 2 diabetes who are looking to lower their A1C, which is the two- to three-month average measurement of blood sugar levels. Indeed, research suggests this diet may lead to fast weight loss and potentially lower blood sugar for people with the disease. (13)
When you’re first getting started, it can be helpful to use a blood or breath ketone meter. What these meters do is measure the amount of ketones (the energy source your body is switching to) in your blood or your breath. Knowing those amounts and seeing how they increase or decrease depending on what you’re eating daily can often be a motivating and helpful indicator of the transition occurring in your body.
In another study that involved mice with brain tumors, administration of 65 to 75 percent of the recommended daily calories helped reduce tumor growth by 35 and 65 percent among two different test groups. Total carb consumption was restricted to 30 grams only.14 A different mice study strictly limited carb consumption to 0.2 percent only, which helped reduce the growth of glucose-fermenting tumors.15
This is an adaptation period, where we’re essentially re-training our muscles and our brain to use fat as the primary fuel source instead of glucose. This adaptation can take a couple of weeks to a couple of months. As a hallmark of being keto-adapted and not just in ketosis, the skeletal muscles are able to burn fat directly for fuel, and the brain relies on the higher volume of ketones in the blood as its main source of energy.

It comes down to simple mathematics. In order to stay in ketosis, you need to eat a very very low number of carbs. And if you eat too much protein, this can actually knock you out of ketosis as well. Therefore, if you’re eating almost no carbs, and you are eating moderate amounts of protein, the ONLY remaining macronutrient you can consume to fill you up each day would be fat. Add in that consuming fat allows you to stay in ketosis, and you are consuming a high fat, medium protein, low carb diet.
